Certa is rated 4.4 out of 5 by 25.
Rated 3 out of 5 by from Not sure yet Bought it about a month ago because of the clear ray system. So far we can't use it for more than 3 or 4 days and we have to change the water. It's our first hot tub so I don't have anything else to compare it to. After doing some research I find that the water should last at least a month and most often I read 3-6 months. So far we've tried the chemicals that came with it, poor results. We've tried a natural cleaning system, so far no better results... leaving me to question whether the clear ray filter system lives up to the claims. Water is cloudy and mildewy after two days.

Rated 5 out of 5 by from Enjoyment with a capital E! We bought the Sundance Certa hot tub about a month ago and have been enjoying it about 3 or 4 times a week! If you've got sore muscles or just want to relax, climb in and you will definitely be relaxed. The different seating positions offer massages to all different parts of your body! The waterfall and the lighting just adds to the experience! We have had zero issues with the tub and just love it! Construction of the tub is very high quality, the controls are easily understood and it is just fun to enjoy!

Rated 5 out of 5 by from grand kids love it! The first words out of the grand kids mouth when they come to visit is " can we get in the hot tub Grandma?" They love it and so do we. We had shopped around and thought this was the best spa value for the money. Napa valley hot tubs were great! Thanks, Gary & Jayne

Rated 5 out of 5 by from Great Spa! This is the second spa we have purchased. The original was purchased about 5 years ago and we had to leave it at the house when we sold the property. We liked the spa so much that we just ordered the same exact model. Great for the price and powerful jets.

Rated 5 out of 5 by from An excellent spa that could use one upgrade I had owned a Sundance Maxxus Spa for 25 years and it was a delight. The only problem that it had that was a a genuine problem was the fact that way back the tub surround was made of wood rather than a more durable plastic. Other than that I think I had 2 repairs. I replaced a motor and a sensor. The total for both was about $400. Not bad for 25 years. However, I did go through 3 wood surround kits, the last of which was the end of stock at the factory. I did paint it so it had more protection and it lives on having sold the house a short time ago. This time I did not need as large a spa and the Certa filled the bill perfectly. There are a few bells and whistles that the 880 series has that the 780 doesn't but they aren't things I care about. A decorative waterfall is more of a distraction to relaxation than a positive feature. I would pay not to have it. The only thing I would prefer about the 880 series is the style of water filtering which I feel is superior to the system that the 780 series uses. It's not a major difference and certainly not worth the extra few thousand dollars that the 880 series costs, but I guess they have to hold on to some features in order to upsell to the 880. All in all I am very pleased with the unit. I am very compulsive and examined more brands and types of spas that I care to think about. This is a very nice unit and I recommend it.
